GAP to Cytoscape Quiver Viewer

INPUT

Force vertices to be labelled by numbers Force arrows to be labelled by alphabets

QPA quiver with relations

Relations detected here override the relation array.

Relation array

Optional fallback input.

Use mousewheel to zoom in/out. Click-and-drag on canvas/edge to pan.
Shortening the distance between vertices connected by multiple arrows may clarify the arrows.

Quiver Input

For quiver input with relations:

                            Quiver( [.. list of vertices ..],
                            [..[src,tar,arr_name]..] ) [ ... list of relations ... ]
                        

"Quiver()" can be omitted. Relations must be the last array and cannot be 2-dimensional. Relations in the QPA quiver code have priority over those in the relation array.

Relation Syntax

Relations can be written in the format "(scalar1)*arrow1*arrow2*... + (scalar2)*...". Scalar coefficients are optional; a monomial such as "a*b" is treated as "(+1)*a*b", and "a*b - c*d" is treated as "(+1)*a*b+(-1)*c*d".

Relation Editing

To edit a relation, select one relation in the relation display, then press Edit relation.

To add relation(s), press Add relation(s), then type in the highlighted entry area. Press Enter to save. Press Shift+Enter to insert a new line. You can use one relation per line or separate relations with commas.

Warnings and Limitations

Finite field detection is available only for characteristics at most 61.
